Peer-to-peer approaches bring one perfect alternative for the Web content search. However, how to search and retrieve the data based on the content query is still an open problem for peer-to-peer systems. In this paper we propose History-based Multi-keywords Search(HMS) in unstructured peer-to-peer systems, which only requires each peer to maintain partial query information of its neighbors, and exploit...
In mobile peer-to-peer networks, the incentive mechanism has to be provided for peers' participation as both resource suppliers and intermediaries (routers). In this paper we propose our solution to the incentive problem for intermediaries of message routing. We provide the domination- set-based peer-to-peer searching algorithm with economic models, which achieves motivating peers' corporation in...
We consider the problem of building Web information retrieval mechanism through distributed solution based on Peer-to-Peer technology. We describe a prototype system called IOSUW (Interest-Oriented Search Union of Web servers) that is currently under development in our group. IOSUW provides a highly distributed global indexing and query execution services which are based on the organization of P2P...
BitTorrent is a very popular P2P file sharing system. It has been successful at distributing large files quickly and efficiently. Embedded in BitTorrent is a set of incentive mechanisms to encourage sharing and contribute, and prevent systematic free-riding. In this paper, a fluid model with two classes of peers is used to capture the effect of free-riding in a BitTorrent system. With the model, we...
The variance of user interest is a significant factor for designing peer-to-peer content-based retrieval system which leads to the birth of this paper. This paper gives the preliminary scheme to solve the problem of Web search of Internet scale. All the personalized peers form an interest-oriented Web server union (IOWSU) by employing structured P2P routing mechanism. After a query request from a...
